When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

This diff is rather large, but it's just simply removing unnecessary headers
, remove some lint-style comments, add missing void to functions without args,
also some function prototypes (extern) were missing their args, so I added them
as they were defined in hack.h

OK tb@ on separate diffs

hack expects to be able to read ^Z as a normal character so disable
SUSP in the termios settings. Presumably this is how things worked
before the conversion to termios. Fixes suspend/resume in hack.

Annotate funcs with __attribute__((printf(...))) and clean up the fallout:
* lots of foo(str) --> foo("%s", str) transformations
* one totally insane foo(fmt, ap) --> vfoo(fmt, ap) conversion: how did
this ever work?
* prefer const char[] over char* for static format strings, as it lets
gcc check the format and eliminates an unnecessary pointer

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

use vprintf, as obvious; frederik.deweerdt@laposte.net

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

A few more includes discovered in a -fno-builtin compile

De-register, ANSIfy, clean up.

hack is free
